The present invention relates to new and useful improvements in methodand means for constructing roofs and more particularly roofs of the dometype.

The principal object of the present invention is to provide a roofconstruction which will be more durable and reinforced than present roofconstructions without increased cost of construction.

Another important object of the invention is to provide a roofconstruction which will eliminate complicated and unsightly roof trussesand other forms of brace means.

Other important objects and advantages of the invention will becomeapparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational view of the dome structure withcertain sections constructed.

Figure 2 is a top plan view of the dome structure showing certainsections of the roof under construction.

Figure 3 is a vertical sectional view through the roof.

5 Figure 4 is a sectional view taken substantially on the line 4-4 ofFigure 2.

Figure 5 is a diagrammatic view disclosing a plan for one of the roofstructures.

Figure 6 is a fragmentary elevational view showing the bracing means.

Referring to the drawings wherein like numerals designate like parts, itcan be seen and understood that the roof can be of circular, triangular,square or various polygonal shapes without departing from the spirit ofthe present invention.

As can be seen in Figure 2, the roof is first constructed with aplurality of converging runners 5 converging to the part 6, andextending from the outer frame 1 are the multiplicity of ribs 8 betweeneach adjacent pair of runners 5.

These ribs 8 extend in parallel relation to each other. Extending backand forth between each pair of ribs 8 are the brace members 9, the end45 portions of the brace members 9 being beveled off as suggested inFigure 6 and disposed in abutting relation with respect to each other,at which abutting points the brace members are secured (Cl. 10S-1)together and to the ribs 8 by bolts l0. As is shown in Figure 6, a pairof bolts Ill--l extend through the rib 8 for securing four end portionsof brace members 9 to the rib 8. Thus there is an economy of bolts andlabor in connecting the brace mem- 5 bers to the ribs 8.

Disposed over the ribs 8 and under the same is the sheathing ID. Thesheathing at the outside of the roof is provided with the usual roofcovering iii and a suitable covering Il is provided for the insidesheathing.

As suggested in Figure 4, it is preferable that the runners 5 beconstructed of a pair of elongated members l2-l2 each having the spacerstrip I3 and also a pair of flange portions of the angle members I4-l4extending between the same as suggested in Figure 4. This rmlyreinforces each of the runners. A nailing strip of wood, preferably, isdisposed along each of the runners 5 and this is denoted by numeral I6.L

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A roof construction comprising an outer frame, inwardly disposed runnersconverging to a mid- 30 point, ribs between the runners and extendinginwardly from the outer frame and being connected at their inner ends tothe runners, said ribs being disposed in parallel relation with respectto each other, a covering for the ribs and runners, and brace meansbetween the said ribs, said brace means consisting of diagonallyextending brace members between each pair of ribs with their endportions in abutting relation with the ribs, the ends of the bracemembers of one pair of ribs terminating in the plane of the ends of thebrace members of an adjoining pair of ribs and common connecting meansfor the ends of a pair of brace members at opposite sides of the rib,the extremities of adjoining brace members abutting to brace each other.
